luke has 9 markers. calan has 4 more markers than luke. how many markers does calan have? which bar model shows how many markers each person has?

Answer

Explanation:

Step1: Identify Luke's markers

Luke has 9 markers.

Step2: Calculate Calan's markers

Calan has 4 more than Luke, so we add 4 to Luke's 9 markers. The expression is $9 + 4$. $9+4=13$

Step3: Analyze bar - models

We need a bar - model where Luke's bar represents 9 markers and Calan's bar has the same length as Luke's bar (9 markers) plus an additional part representing 4 markers.

Answer:

Calan has 13 markers. The correct bar - model is the one where Luke's bar has a length of 9 and Calan's bar has a length of 9 with an additional segment of 4. So the third bar - model.
